Eaton Series C NG31200WA12S03X03Y07 Molded Case Circuit Breaker - Aux Switch & Shunt Trip
Part Number: NG31200WA12S03X03Y07
Manufacturer
Eaton
Part number
NG31200WA12S03X03Y07
Quick Summary
Eaton Series C molded case circuit breaker protects industrial power feeders in switchgear and panels. Engineers often contend with nuisance trips, downtime, and complicated remote shutoffs when protection devices aren’t fast or selective. Certification considerations to confirm during procurement include CE, IP, and SIL compatibility; review the official datasheet for final approvals. With a 3-pole design, 1200 A frame, and built-in Aux Switch and Shunt Trip, this device streamlines control and remote protection. In practice, it supports reliable protection in heavy-distribution panels while offering installation compatibility with standard MCCB assemblies. That combination reduces downtime, enhances safety, and helps meet stringent plant reliability targets.

FAQs
NG31200WA12S03X03Y07 requires a 3-pole mounting arrangement suitable for panels designed for 1200 A protection. Ensure sufficient space for the 9 inch deep, 16 inch tall, and 6 inch wide footprint, maintain clearance for cooling, and verify control wiring routes for the Aux Switch and Shunt Trip. The unit weighs 47 lb, affecting handling and mounting hardware selection. Follow the catalog installation instructions to preserve protective performance and accessibility for testing and maintenance.
Yes. The NG31200WA12S03X03Y07 includes an Aux Switch and a Shunt Trip, enabling remote shutdown and selective tripping within control circuits. This supports remote interlocks and safety interlocks in automation sequences, allowing integration with PLCs, motor starters, and protective relays. When wiring, ensure compatibility with control voltage requirements and long-run signal integrity to avoid nuisance triggering.
This 3-pole 1200 A MCCB is well suited for large motor feeders, switchgear protection, and industrial distribution panels in manufacturing, process industries, and heavy equipment installations. The Shunt Trip and Aux Switch enable remote safety control, while the Series C architecture provides reliable arc-quenching and protection for high-load circuits. Use it where fast isolation and robust protection are priorities.
Verify certifications and approvals through the official Eaton datasheet and supplier records. While the provided data lists general product features, customers should confirm CE, IP ratings, and SIL compatibility with their project specifications and local regulations. Always reference the latest data sheet and your internal compliance requirements before procurement.
Series C MCCBs like NG31200WA12S03X03Y07 are designed for durability, reducing maintenance frequency in demanding environments. Their reliable tripping performance minimizes downtime from faults, while remote shutdown capabilities improve safety and operational readiness. The overall ROI stems from downtime reduction, fewer nuisance trips, simpler field wiring, and streamlined asset management across large electrical distributions.
